Banyan Intercepts Several New Distinct High-grade Silver Veins, including 3,408 g/t Ag over 1.4 m, at AurMac, Yukon

VANCOUVER, BC / ACCESS Newswire / March 16, 2026 / Banyan Gold Corp. (the "Company" or "Banyan") (TSX-V:BYN)(OTCQB:BYAGF) is pleased to announce it has intersected several new, distinct high-grade silver ("Ag") veins at its AurMac Project ("AurMac"), Yukon, Canada.

Airstrip Highlights:

  • AX-25-799 - 3,408 g/t silver over 1.4m, within 352.64 g/t Ag over 13.7m

Powerline Central Highlights:

  • AX-25-810 - 880 g/t silver over 1.5m, within 273.35 g/t Ag over 4.8m, AND 248 g/t silver over 1.0m within 114.52 g/t Ag over 4.1m

  • AX-25-819 - 20.35 g/t silver over 5.8m and 27.43 g/t silver over 7.7m

  • AX-25-821 - 731 g/t silver over 0.8m within 93.17 g/t silver over 7.5m

Aurex Hill Highlights:

  • AX-25-786 - 55.55 g/t silver over 2.8m

Powerline Southwest Highlights:

  • AX-25-788 - 138.10 g/t silver over 0.5m

"The ongoing discovery of new high-grade Keno-style silver mineralization demonstrates that the AurMac project remains underexplored with high discovery potential," said Tara Christie, President and CEO. "Our plans for 2027 will provide meaningful catalysts for Banyan to continue to re-rate, with our upcoming MRE, PEA, and 40,000 m strategic drill program at AurMac, along with 10,000m focused on our regional targets."

Figure 1: Silver mineralization highlights intersected across the AurMac deposit. At least eight distinct Keno veins have been identified across an approximately 2km x 3km zone, centred roughly on the AG-1 vein (see Figure 2).
Figure 2: Plan map of highlight silver intersections in Powerline Central in the AG-1 vein (see Figure 3 for relationship between AG-1 and sub-parallel AG-2 and AG-3 veins).
Figure 3: Cross-section A-B in Powerline. Silver intersections within drillholes AX-25-810, -819, and -821 are consistent with late brittle feature for the AG-1 vein intersected in drillhole AX-21-142 and AX-25-803 (see news releases dated October 29, 2025 and January 22, 2026). Two sub-parallel veins have been identified adjacent to the AG-1 vein intersected in holes AX-21-142 and AX-25-803; AG-2 and AG-3 are north and south of AG-1, respectively (magenta veins and dashed traces above). Block model for Au MRE included to highlight cross-cutting nature of silver mineralization.

Analytical Method and Quality Assurance/Quality Control Measures

All diamond drill core was systematically logged and photographed by Banyan geology personnel. All core samples (HTW and NTW diameter) were split on-site at Banyan's core processing facilities. Once split, half samples were placed back in the core boxes with the other half of split samples sealed in poly bags with one part of a three-part sample tag inserted within. Samples were delivered by Banyan personnel or a dedicated expediter to the Bureau Veritas, Whitehorse preparatory laboratory where samples are prepared and then shipped to Bureau Veritas's Analytical laboratory in Vancouver, B.C. for pulverization and final chemical analysis.

Core splits from 2025 reported in this news release were analysed by Bureau Veritas of Vancouver, B.C., utilizing the four-acid digestion ICP-ES 35-element MA-300 or ICP-ES/MS 59-element MA-250 analytical package with FA-450 50-gram Fire Assay with AAS finish for gold on all samples. Samples returning >10 g/t Au were reanalysed by fire assay with gravimetric finish on a 50g sample (FA-550). High-grade samples with documented visible gold are also analysed using metallic screen fire assay (FS-652). Samples returning >200 g/t Ag (MA250 or MA300) were analysed by mutli-acid digestion ICP-ES MA370. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 50g sample (FA550). If samples returned > 10,000 g/t Ag, they were analysed by fire assay 2g sample (FA501). Bureau Veritas is an accredited lab following ISO/IEC 17025:2017 SCC File Number 15895. A robust system of standards, ¼ core duplicates and blanks has been implemented in the 2025 exploration drilling program and is monitored as chemical assay data becomes available. Historic 2019 Ag samples were analysed at BV by aqua regia digest ICP-ES/MS 37-element AQ200 (2019). Historic 2012 samples were analysed at ALS by 34-element four acid digest ME-ICP61. If samples returned > 100 g/t Ag, a 0.4g sample was analysed by four acid digest ICP-AES Ag-OG62. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 30g sample (Ag-GRA21). Historic 2000 Ag samples were analysed at ALS by ICP-MS Ag 9225.

About Banyan

Banyan's primary asset, the AurMac Project is located in the Traditional Territory of First Nation of Na-Cho Nyäk Dun, in Canada's Yukon Territory. The current Mineral Resource Estimate ("MRE") for the AurMac Project has an effective date of June 28, 2025 and comprises an Indicated Mineral Resource of 2.274 million ‎ounces of gold ("Au") (112.5 M tonnes at 0.63 g/t) and an Inferred Mineral Resource of 5.453 Moz of Au (280.6 M tonnes at 0.60 g/t ) (as defined in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition ‎Standards for Mineral Resources & Mineral Reserves incorporated by reference into NI 43‑101). The 303 square kilometres ("sq km") AurMac Project lies 40 kilometres from Mayo, Yukon. The AurMac Project is transected by the main Yukon highway and benefits from a 3-phase powerline, existing power station and cell phone coverage.
